Photonic Fabric is Marvell's optical interconnect platform for chiplet-based, multi-rack AI scale-up networks.
Photonic Fabric is Marvell's optical interconnect platform for accelerator scale-up. Its photonic I/O chiplets place optical links close to XPUs and switches, supporting high-bandwidth connections beyond the reach of copper links.
Marvell positions the platform for multi-rack scale-up and shared-memory systems. The company gained the technology through its acquisition of Celestial AI and now offers it within its data center connectivity portfolio.
